Abstract: The present invention is a portable electronic video display. The display is configured to be worn on the arm or wrist of a user, or stored in a pocket or backpack. The display is raised to eye level and the user looks through an eyepiece to view the video display. Control buttons are located on the display for generating point and click type commands. The display is meant to be used remotely from a computer. The computer would be worn or carried by the person or simply be free standing, some distance away. The computer is configured to convert video signal into a serial data stream and then transmit that stream via an RF signal. The display then receives that signal and converts it back into a video signal, displaying it on a miniature electronic video display. That image is then magnified through various optics to present a final image to the user. The point and click commands are separately transmitted back to the computer, where they are received and acted upon.

Abstract: The present invention is a fully functional hand held computer having a see through display. An external viewing arrangement, such as a monocular scope, is used to view the operator's immediate surroundings. Optical images from the scope are superimposed with digital images from a miniature computer display. The resultant image allows the operator to look through the device and view his surrounding while simultaneously viewing and operating the software based applications. The entire device is held like a pair of binoculars and mouse like controls are located adjacent the operator's gripping position.

Abstract: The present invention is a proximity detector for an electronic device. The proximity detector utilizes two capacitors which share a common electrode. The two capacitors are located on the housing of the electronic device. The capacitors are arranged so that when the electronic device is used in its normal orientation, a portion of the operator's body will occlude one of the capacitors, but not the other. The close proximity of the operator's body will change the electric field surrounding the capacitor. Thus, the capacitance of the occluded capacitor will be different than the unencumbered capacitor. A detection circuit is coupled to the capacitors and to the power supply of the device. The circuit uses very little power, and maintains the electronic device in a standby or powered down mode. Only when the circuit detects a difference in the capacitance generated by the two capacitors, will it allow full power to be delivered to the electronic device.

Abstract: A smart fastener having corrosion detection features. Within the fastener is a corrosion detecting array that receives an electrolyte that corrodes sacrificial materials formed on electrodes of the corrosion detecting array. The materials are the same as those materials which are secured, fastened, or attached by the fastener. There is parallel corrosion of the sacrificial materials and the attached materials since the electrolyte which is channeled via capillary tubes into the corrosion detecting array is the same electrolyte that is in the environment of the fastened materials. Other electrodes sense various properties of the electrolyte. Information sensed by the corrosion sensing electrodes of the array is in the form of very small electrical signals which are amplified and stored in an analog storage memory. A clock and addressing device time stamps and address the signals.

Abstract: A conformal telemetry package comprises a complete system including sensors, data acquisition components, a controller, RF transmitter, antenna and battery. The package is approximate 0.1 inch thick and is flexible and capable of conformable mounting to a curved surface. This package includes a printed circuit antenna such as a microstrip patch antenna. The bottom of the package is coated with an adhesive permitting the system to be mounted on surfaces such as the leading edge of an air foil. The package is kept thin and flexible by using multiple layers of flexible dielectric such as Teflon and extremely high levels of circuit integration.

Abstract: Pairs of cross coupled transistors are configured as a bistable regenerative circuit. Isolation means, such as diodes or transistors, are provided in the cross coupling paths to ensure that if the logic state of one transistor is temporarily changed by radiation striking the circuit, the logic state of the other transistor it is paired with will not change and the logic state of the unchanged transistor will be utilized to maintain the logic state of the other pair of transistors. CML, DTL and SDFL circuits are disclosed as the preferred embodiments.
